Capacitive sensor

Capanivo® - CN 8100

Application area

The capacitive level detector Capanivo® 8100 is used in storage and process vessels as a full, demand and empty detector in all liquids. Due to different probe versions, a suitable solution will be found for every installation setting. A robust construction allows service at process temperatures up to +125°C and a process overpressure up to 25 bar.
